Muc1 bioactivation contributes to lung fibrosis

2019

INTRODUCCIÓN La fibrosis pulmonar idiopática (FPI) es una forma específica de neumonía intersticial fibrosante, progresiva, crónica y de causa desconocida. Recientemente se ha propuesto que la FPI surge a partir de episodios repetidos de daño en las células epiteliales alveolares, lo cual puede estar asociado con una liberación de mediadores profibróticos (como el factor de crecimiento transformante β1 (TGFβ1)), fomentando la activación descontrolada de fibroblastos, transformaciones celulares en células mesenquimales de tipo miofibroblasto y una acumulación excesiva de matriz extracelular en el intersticio pulmonar, lo cual destruye la arquitectura alveolar normal e interrumpe el intercamb…

Papel del estrés oxidativo y del tejido adiposo en la pancreatitis aguda experimental

2013

La pancreatitis aguda es un proceso inflamatorio agudo del páncreas con afectación variable de otros tejidos y sistemas orgánicos alejados. La incidencia de la pancreatitis aguda en la Unión Europea y Estados Unidos varía de 5 a 30 casos/100.000/año (Ellis y cols., 2009). La mortalidad en pacientes con pancreatitis aguda es alrededor del 5%, pero este porcentaje aumenta al 17-20% en pacientes con pancreatitis necrotizante (Pandol y cols., 2007). La participación del estrés oxidativo en la pancreatitis aguda se ha podido demostrar en la depleción precoz de glutatión reducido (GSH) y su precursor, la cisteína, que se mantiene y precede a la formación de edema pancreático. Este descenso en los…

Patients' and physicians' preferences for type 2 diabetes mellitus treatments in Spain and Portugal: a discrete choice experiment.

2015

Objective: To assess Spanish and Portuguese patients' and physicians' preferences regarding type 2 diabetes mellitus (T2DM) treatments and the monthly willingness to pay (WTP) to gain benefits or avoid side effects. Methods: An observational, multicenter, exploratory study focused on routine clinical practice in Spain and Portugal. Physicians were recruited from multiple hospitals and outpatient clinics, while patients were recruited from eleven centers operating in the public health care system in different autonomous communities in Spain and Portugal. Preferences were measured via a discrete choice experiment by rating multiple T2DM medication attributes. Data were analyzed using the cond…

The impact of direct acting antivirals on hepatitis C virus disease burden and associated costs in four European countries

2021

Eliminació del VHC; Punt d'equilibri; Infecció d'hepatitis C Eliminación del VHC; Punto de equilibrio; Infección de hepatitis C HCV elimination; Break-even; Hepatitis C infection Background and Aims We assessed the clinical and economic impact of direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) in England, Italy, Romania and Spain. Methods An HCV progression Markov model was developed considering DAA eligibility and population data during the years 2015-2019. The period of time to recover the investment in DAAs was calculated as the cost saved by avoiding estimated clinical events for 1000 standardized treated patients. A delayed treatment scenario because of coronavirus di…

Two cases of monomicrobial intraabdominal abscesses due to KPC - 3 Klebsiella pneumoniaeST258 clone

2011

Abstract Background Knowledge of the etiology of pyogenic liver and pancreatic abscesses is an important factor in determining the success of combined surgical and antibiotic treatment. Literature shows geographical variations in the prevalence and distribution of causative organisms, and the spread of Klebsiella pneumoniae carbapenemase-producing bacteria is an emerging cause of abdominal infections. Case presentation We herein describe two cases of intra-abdominal abscesses due to monomicrobial infection by Klebsiella pneumoniae Sequence Type 258 producing K. pneumoniae carbapenemase 3 (KPC-Kp). In case 1, a 50-year-old HIV-negative Italian woman with chronic pancreatitis showed infection…

SARS-CoV-2 and its impact on the cardiovascular and digestive systems – The interplay between new virus variants and human cells

2023

Since infection with the novel coronavirus SARS-CoV-2 first emerged in Wuhan, China, in December 2019,the world has been battling the pandemic COVID-19. Patients of all ages and genders are now becoming infected with the new coronavirus variant (Omicron) worldwide, and its subvariants continue to pose a threat to health and life. This article provides a literature review of cardiovascular and gastrointestinal complications resulting from SARS-CoV-2 infection. COVID-19 primarily caused respiratory symptoms, but complications can affect many vital organs. SARS-CoV-2 binds to a human cell receptor (angiotensin-converting enzyme 2 – ACE2) that is predominantly expressed primarily in the heart a…

Considering syntrophic acetate oxidation and ionic strength improves the performance of models for food waste anaerobic digestion.

2021

Current mechanistic anaerobic digestion (AD) models cannot accurately represent the underlying processes occurring during food waste (FW) AD. This work presents an update of the Anaerobic Digestion Model no. 1 (ADM1) to provide accurate estimations of free ammonia concentrations and related inhibition thresholds, and model syntrophic acetate oxidation as acetate-consuming pathway. A modified Davies equation predicted NH3 concentrations and pH more accurately, and better estimated associated inhibitory limits. Sensitivity analysis results showed the importance of accurate disintegration kinetics and volumetric mass transfer coefficients, as well as volatile fatty acids (VFAs) and hydrogen up…

Differential effects of CB1 neutral antagonists and inverse agonists on gastrointestinal motility in mice

2010

Background  Cannabinoid type 1 (CB1) receptors are involved in the regulation of gastrointestinal (GI) motility and secretion. Our aim was to characterize the roles of the CB1 receptor on GI motility and secretion in vitro and in vivo by using different classes of CB1 receptor antagonists. Methods  Immunohistochemistry was used to examine the localization of CB1 receptor in the mouse ileum and colon. Organ bath experiments on mouse ileum and in vivo motility testing comprising upper GI transit, colonic expulsion, and whole gut transit were performed to characterize the effects of the inverse agonist/antagonist AM251 and the neutral antagonist AM4113. As a marker of secretory function we mea…

Laparoscopic approach in abdominal emergencies: a 5-year experience at a single center.

2012

Background. Laparoscopy is ever more common in both elective and emergency surgery. In fact, in abdominal emergencies it enables the resolution of preoperative diagnostic doubts as well as treatment of the underlying disease. We present a retrospective study of the results of a 5-year experience at a single center. Patients and methods. Between September 2006 and August 2011, 961 patients were treated via laparoscopy, including 486 emergency cases (15 gastroduodenal perforation; 165 acute cholecystitis; 255 acute appendicitis; 15 pelvic inflammatory disease and non-specific abdominal pain [NSAP]; 36 small bowel obstruction). All procedures were conducted by a team trained in laparoscopic su…
